3D audio effects are a group of sound effects that manipulate the sound produced by stereo speakers, surround-sound speakers, speaker-arrays, or headphones. This frequently involves the virtual placement of sound sources anywhere in three-dimensional space, including behind, above or below the listener. [1]
The iPhone 12 and iPhone 12 Mini, like the iPhone 12 Pro and iPhone 12 Pro Max, are the first iPhone models from Apple to no longer include a power adapter or EarPods headphones found in prior iPhone models; however, a USB-C to Lightning cable is included; this change was retroactively applied to other iPhone models sold by Apple, such as the ...
These naming variations are also used for the 3.5 mm connectors, which have been called mini-phone, mini-stereo, mini jack, etc. RCA connectors are differently-shaped, but confusingly are similarly-named as phono plugs and phono jacks (or in the UK, phono sockets). 3.5 mm connectors are sometimes—counter to the connector manufacturers ...
Apple's iPhone 7 and newer models lack a headphone jack (released in September 2016), and until September 12, 2018, included a Lightning to 3.5mm dongle. iPhone models from the iPhone 7 to the iPhone X also shipped with a Lightning-to-3.5mm headphone jack adapter, enabling customers to connect 3.5mm headphones to a Lightning port.
Active noise-cancelling headphones use a microphone, amplifier, and speaker to pick up, amplify, and play ambient noise in phase-reversed form; this to some extent cancels out unwanted noise from the environment without affecting the desired sound source, which is not picked up and reversed by the microphone. They require a power source ...
In sound technology, personal sound refers to a range of software solutions that customize an audio device's sound output to match the listener's unique hearing sensitivities. [1] The technologies aim to optimize the sound quality in the audio device to ensure they best fit the hearing perception of each unique listener.
In a phonograph reproducer, the diaphragm is a flat disk of typically mica or isinglass that converts the mechanical vibration imparted on the buttress from the recorded groove into sound. In the case of acoustic recording the reproducer converts the sound into the motion of the needle that scribes the groove on the recording media.
In a crystal radio, the user would tune the radio to a strong local station if possible and then adjust the cat whisker until the station or radio noise (a static hissing noise) was heard in the radio's earphones. [25] This required some skill and a lot of patience. [6]
